Abstract

1286776 Turbomachine rotor blade fixing GENERAL MOTORS CORP 19 April 1971 [21 July 1970] 26578/71 Heading FIT The roots 8 of a compressor blades 7 are mounted in generally axially extending slots 10 in a rotor rim 4 and retained against movement out of the slots in a forward direction by means of retainer plates 12 mounted in an annular groove 14 defined between radially outer and inner annular flanges 15, 16 on the forward face of rim 4. Movement of each blade in a rearward direction is prevented by a lug 11 on each root 8 abutting a face of rim 4. The rotor is assembled by inserting all the roots 8 in their respective slots 10 and then inserting a retaining plate 12 so that its inner edge engages behind flange 16 of groove 14 and its fingers 20, 21 about adjacent roots 8. In this position, Fig. 3 (not shown), tab 23 is disposed against the front of flange 15. Plate 12 is then slid circumferentially to the left, as shown in Fig. 2, until fingers 20, 21 engage behind flange 15 and tab 23 is disposed in front of a root 8. The plate 12 is locked in position by bending tab 23 inwards into a recess 18 in root 8. The remaining plates 12 are then inserted one by one, the tab 26 of each plate abutting the end 28 of the adjacent plate.
